A Walk Through La Pedrera - Casa Mila - Barcelona
While visiting Barcelona we went to La Pedrera - Casa Mila. I bought tickets in advance for this building. It was very busy and you basically follow along with the crowd.
Side Note - we also visited Casa Batllo on the same day. Casa Batllo is the busiest of all the buildings. I bought the top tier ticket which allowed us to see the apartment, but also allowed us priority access over the other lines. I didn't make a video there since there were too many people - but it was our favourite building out of the 5 plus Park Guell, that we visited.
